HINGE.

Application filed May 2, 1923.

T 0 all whom it may concern:

Be it known that we, JOHN Q. SHERMAN and ALBERT lvlnrznnn, citizens of the United States, and residents of Dayton, in the county of Montgomery, and State of Ohio, have invented certain new and use ful Improvements in Hinges, of which the following is a full, clear, and exact description, reference being had to the drawings accompanying this specification.

Our invention relates to devices which serve as a hinge, but in which the parts hinged together can be lifted apart without dismounting any mechanism from either portion thereof. I

In various kinds of mechanism, there is a need for a hinge device which will be easy to set together and the hinged parts easily lifted apart. Our invention provides such a hinge.

It is also desirable in various structures to arrange the hinging together two members in such a relation that the one will be lifted away from the other when the hinge is flexed.

Such devices are, for example, the lids on talking machines, the covers for typewriters, autographic registers, sewing machines, bodies on wagons, and many other instances, where it is not desirable to have the hinged member strike the member to which it is hinged when said member is turned back, or opened.

Our invention provides for 'thlS cont1ngency also. Furthermore our invention provides a lid or cover hinge, in which thearrangement can readily be such that the lid cover, wagon body or what not is held in its open position by gravity, due to its being overbalanced, and liftedaway from its supporting element.

It is our object to provide for the various features above noted with as simple a structure as possible, and we accomplish said objects by that certain construction and arrangement of parts to be hereinafter more specifically pointedout and claimed.

In the drawings:

Figure 11 is a detail of the hinge members shown in Figure 10.

Figure 12 is a detail of the usual form or fixed member of our hinge.

Figure 13 is a detail of the usual form of movable member of our hinge.

Referring first to Figures 12 and 13, it will be noted that the hinge is made up on a base 1, within which is arranged a pocket 2, terminating away from the standard portion 4, in a hook 3. The standard portion 4 considering its usual relation with a fixed part on which it is mounted, has a rearwardly bent upper'portion 5, terminating in a forwardly directed hook 6.

The hook is rearwardly from the central vertical line drawn through the lower portion of the standard, and the forward outline of the standard is curved.

The rear outline of the standard is also curved and is formed into a downwardly or between the two hooks on the standard.

are rollers 9, 9, which straddle the standard. The mounting plate has also a hook 10 to engage the hook 3, when the mounting plate is at its lowermost position with the roller at the lower end of the standard.

Prior to referring to the drawings showing the hinge device in use, it may be noted that the upper portion of the standard may be in the shape of a pawl (dotted line 11} pivoted at dotted line 12 on the standard, which standard would cease just above this pivot.

In operation the hinge device is assembled by dropping the two rollers over the standard, so that they rest at its lower end. When using the hinge the part hinged is swung upwardly and rearwardly, whereupon the one roller will ride over the forward edge oi the standard, and the other will ride over the rearward edge thereof. The upper roller will find its stopping point in the upper hook and the lower roller will find its stopping point in the lower hook. The hinged member will then be lying in an overbalanced position and cannot fall backward because of the hook.

The two rollers serve as pivots for the movable member, and the standard is designed so that there will not be suliicient over-all width, to preventthe user from so manipulating the roller carrier as to lift it direct off of the standard. In swinging back the roller carrier, the carrier first pivots on the rear roller until the forward roller has reached the bend in the standard below the upper hook. The whole carrier is then lifted up away from the base of the standard, and the lower rollers ride up on the rear of the standard, until it catches in its hook.

In the closing down of the hinge, the rearmost roller first rides down the rear of tne standard and thenserves as the pivot for the return of the other roller to its lowermost position. The hooks 3 and 10 engage each other when the roller carrier is in its lowermost position.

This permits of locking down the roller carrier by engaging the mounting element at some other point, by a latch, key con trolled bolt, or other means.

Referring to the special illustrations of modes of use, in Figures 15, we show a motor truck having a bed 20, on which is erected at each rear corner one of the standards, as above described, same being numbered in a like manner. The truck body 21 has mounted thereon, a roller carrier and pair of rollers, as above described. The side frames of the bed, have hooks 22 to engage hooks 23 on the wagon body when the body is lowered.-

The tail gate 25 of the body may be equipped in two or more ways, for automatically latching and opening with the manipulation of the body. lVe have shown pullevs 26 and cabl s 27 for raising and lowering the body. The gate 25 may be equipped with a cross rod 28, which when the body is lowered will seat in a pair of depressions 29 in the frame, behind raised knobs or the like 80. When the body is raised, the gate will ride up from its engagement and be free to open, at the time the body has swung to a position just past the vertical. The form shown in Figures a and 5, illustrates two bearing plates 31 on the two lower corners of the tail gate. These plates ride behind curved plates 32, erected at the two rear corners of the frame. The curve is calculated to release the tail gate at the same point as the cross rod is released in the form first described.

In. lowering the body in either form, the gate can easily be'swung in behind the plates or lugs so that it will seat behind whatever projections are provided.

Thus our device in this instance gains the advantage of elevating the body sutficiently to free a tail gate, as well as providing a hinge which forms a very strong support for the body at all times. In mounting the body on the bed it will be set at a slant from the horizontal and then the rollers dropped down over the standard. In use this position will never be reached, as the lower roller remains at the bottom of the standard, serving as a pivot, until the upper roller rides up on the hump of the standard, and when moving up on the standard or down, the body will never move naturally to lift away therefrom.

In the talking machine instance, we show a cabinet 130, having a lid 131. The lid is provided with the rollers and carrier, having the hook, and the body is provided with the standard. In this instance, the standard terminates after the hump 32, and a pawl 33 is .used, having the upper hook 33 and the lower hook 34. The advantage of using the pawl is that it will tip down to the position shown in thedrawing, when the lid is closed, and will raise to a position to complete the standard as indicated in Figure 12 when the lid is raised. When the lid is lowered the pawl gives way before the sloping top of the lid, permitting the top of the lid to be lower than it could be if the standard were in one piece.

In Figure 7, we show an autographic register having a base 40, and a cabinet top 41. The standards are on the base, as are the hooks 3, the roller carrier-and rollers are here shown on the inside'of the cabinet, which lies outside of the standards with the rollers projecting inwardly to straddle the standards.

In Figure 8 the form of standard is used in which the upper portion is in the form of a pawl 50. This pawl is used here so that the back of the cabinet can be very close to the standards, and still the lid be overbalanced when open, permitting gravity to hold it in said open position.

in Figiiire 9, a cabinet is shown having the roller carrier mounted upon it. The lid (Si has a standard at the hinged corners, depending between the rollers, but otherwise like the standards illustrated previously. In this case the pawl is held in position normally by a lug on the side of the cabinet. as at 62, engaging a shoulder 63 on the pawl This locks down the hinged end of the lid when closed. The action of the hinge is practically the same as heretofore described.

In Figure 10, the cabinet has a lid 71, with the standards 72 on the lid, and the rollers 73 on the cabinet; The standard is formed with a shoulder 74, which is wide enough to serve as the abutment against which the rearmost roller engages when the lid is open, and also to ride behind the curve of the case, as indicated at 75, when the lid is closed. This prevents the lid from being lifted at the hinged end, and provides for complete locking down thereof on the cabinet. The form of standard 72 shown in Figure 11, is that of Figure 10, showing the face 76 which rests against the back of the cabinet, and the end hoolr '77, and shoulder 74.

There are other possible modifications and a wide variety of uses to which our hinge may be put, and we have shown a number of instances to make clear the fact that we consider it of general application.

The particular shape, aside from its general characteristics, is not insisted upon, nor do the rollers have to be such, as they may be more studs or other abutments, with like function except for avoiding friction and wear.

The hook for the rearmost roller, shown in all the views, and embodied in the pawl, is not always necessary and may be omitted. Its presence prevents the hinged member rocking on the uppermost roller while being moved from its overbalanced to its vertical position, thereby throwing the rear roller away from the standard and letting the hinged member drop down over the standard without bearing on both sides thereof. In a light structure this action of tipping away may result in the hinged member being lifted clear away from the standards.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is
